Through my graduate assistant position at U-Spatial, I was asked to design this map for inclusion in an academic paper written by Robert McCaa and Nathan Weaver Olson. The paper reconsiders the notion that Francisco Pizarro's second voyage to South America introduced smallpox to the continent. The map is not designed to tell the whole story on its own – it serves as visual support to the more complex narrative offered in the paper, placing the timeline in its proper geographic context.
